Ashes fly back : a novel / by Petersen, Martha Jane.(CARDINAL)619727;
"Hank Lattimer, a young assistant pastor in a vibrant Georgia Presbyterian church, forges an unexpected friendship with Moses Awulu, an African graduate student studying in Atlanta. As the Christmas season approaches, Hank’s church extends a warm invitation to a diverse group of international students but excludes Africans from eating in the church building, which Hank blindly approves. His world is thrown into turmoil as he grapples with the painful realization of his own personal discrimination. Moses severs his ties with Hank and the church and returns to Africa. A year later, Hank is sent as a missionary to Moses’s homeland. Once on African soil, he faces a daunting question: Can he mend the damage he unwittingly helped cause? Ashes Fly Back, a poignant story of friendship and estrangement, explores the global repercussions of discrimination and the paths to racial justice"--

Fly ash facts for highway engineers / by United States.Federal Highway Administration.Office of Technology Applications.(CARDINAL)286883; American Coal Ash Association.(CARDINAL)319143;
Includes bibliographical references (pages 69-70).Fly ash as an engineering material -- Frequent applications -- Use in Portland cement concrete -- Use in stabilized road bases -- Use in flowable fill applications -- Use in grouts for concrete pavement subsealing -- Use in fast track concrete pavement -- Use in structural fills/embankments -- References -- Bibliography.Coal fly ash is a coal combustion by-product (CCB) that has numerous applications as an engineering material; the annual production of CCBs is nearly 82 million metric tons (90 million tons). Since the first edition of this publication in 1986, substantial information has been accumulated regarding the use of fly ash. The purpose of this document is to provide technical information about engineering applications to potential users of CCBs and to advance the use of CCBs in ways that are technically sound, commercially competitive, and environmentally safe.Sponsored by the U.S. Dept. of Transportation through the Federal Highway Administration, performed by the American Coal Ash Association, Inc.

Optimum mixture proportions for concretes containing fly ash and silica fume / by Ozyildirim, H. Celik(Hamdi Celik)(CARDINAL)311389; Halstead, Woodrow J.(CARDINAL)314553; Virginia Transportation Research Council.(CARDINAL)195142;
Includes bibliographical references (page 13).Final report;Concretes with equal water/cement ratios and equal paste volumes of various combinations of cement, fly ash, and silica fume were tested to establish parameters for strength and chloride permeability. Comparative specimens with Type II and Type III cement were tested. The effects of temperature and moisture availability during curing were also evaluated. In general, the laboratory tests showed that, when adequate curing in the 73°F to 100 °F temperature range is provided, concretes with satisfactory early and 28-day strengths and good resistance to chloride ion penetration can be obtained with either type of cement and various combinations of fly ash and silica fume. The cementitious material can be in the range of 30 to 35 percent fly ash and 5 percent silica fume, based on the weight of the cementitious material. Similar specimens cured at 43°F generally did not develop an adequate early strength, and the chloride permeability was high. Combinations of the pozzolans with Type III cement yielded higher strengths and a lower chloride permeability than did similar combinations with Type II cement.Sponsored by the Virginia Dept. of Transportation, in cooperation with the Federal Highway Administration, under contract no.
